What an obvious typo. You clearly must have meant "Do you think Skyrim has to munch hype"; 'much' simply cannot be used as a verb.
But it's actually an interesting question. Skyrim is still a pretty good ways out, but so far, most of the buzz surrounding the game has been produced by the series' own reputation and familiarity with gamers. The studio themselves hasn't, so far, gone on any great marketing bent like a lot of other AAA titles like to do, but it still has managed to become one of the most anticipated titles of the near future.
So, to answer your question, yes, I think Skyrim will simply have to 'munch' its own hype, as it were; hype is always a double-edged sword, but Bethesda seems pretty confident so far that they can live up to the gamers' expectations, so rather than downplay it or try and artificially add to it and risk messing up a good thing, the people at Bethesda would be wisest to simply feed off of the natural anticipation their previous installments and current development news has blessed them with.
Or, as the OP might put it, to simply 'much [sic] it down.' A rather thoughtful perspective; thanks, OP!
